Single-screw testing machines

Single-screw testing machines are used primarily for tests which impose particularly severe demands on load-frame stiffness. Typical applications include low-cycle fatigue tests, creep tests, fracture mechanics tests and tests on springs and ceramics.
Central lead screw testing machine

Key advantages and features

  • Available in 100 and 250 kN versions.
  • Equipped with a central drive-screw, allowing an especially favorable force-flow to be achieved during the test with direct load application to specimen.
  • Design delivers very high load-frame stiffness.
  • Modular construction of complete system allows entire ZwickRoell accessory range to be used (e.g. wide range of extensometers, specimen grips and load cells can be attached).
